Mifare DESFire EV1 MF3ICDH81

[RaveGun]

Hello and thank you for this project.

I would like to able to read the UID of the Mifare DESFire EV1 (MF3ICDH81) type of cards.

I think I have one of the cheapest type of PN532 to Micro USB reader. The PN532 is paired with a CH340E USB to serial chip. I can connect to the reader and read my Phone NFC (interesting a powered off Pixel 6a can still be read). Also it was possible to read the UID of some Ultralight cards.

But when I try to read the above mentioned card, it is not detected.

[USB] PN532 --> hf 14a scan
=>   0000FF03FDD414011700
<=   0000FF02FED51516
=>   0000FF04FCD44A0100E100
ISO14443-A Tag no found

I do not need to do anything else, just to read the UID.

Is maybe the antenna board's antenna design to small / weak? Why will he not detect the TAG?

Thanks.
